Personally id say go with Valium or Clonazepam and stay the hell away from Xanax. While you will get withdrawal from all 3 Xanax has the shortest half life by far of the 3 and the shortest method of action thus you will have to dose much more often and you will go into withdrawals much quicker. Most people i know who have run into trouble with Benzos did so on Xanax.
Currently i am tapering down my Clonazepam from 6mg's a day and now i am down to 5mg's. I can go a good 2 days without experiencing withdrawals. I was thinking about tapering down to 2mg's a day then switching over to 40mg's of Valium a day and staying on that. I could do with the muscle relaxation plus Valium is the easiest one to taper from due to it's super long half life.
Honestly Valium might be your best option because the doses are pretty low compared to high potency Benzos like Clonazepam and Xanax and it's the easiest to taper from. Also as they make Valium pills in 10, 5 and 2mg doses it's much easier to adjust the dose when your tapering off. Hell in Canada atleast they even make a oral solution of 1mg per ml though that might be for pediatric use only.
There's also the 5mg suppositories...I ate them when I had some given to me in those old 08-12 pill parties we had at my pharm dealer's place, when he was in a good mood, he'd throw a bunch of shit on a table, opiates, benzo, muscle relaxants (just yellow houses - cyclobenzaprine, I was a preteen when Soma was removed here), I remember showing him what SteriFilts were and how I shot a 60mg m-eslon in front of him, something he was skeptic about even after using his huge plasma tv and the PC connected to it with his wireless mouse and keyboard. SteriFilts are hard to come by here, not typically given with injection kits, they got cottons good enough for HydromorphContin crushed beads (at least they did until I stopped in late 2012, I think they added something talc-y later, so it ruins those who just snort crushed HMContin pills are now at the same risk of getting a Ritalin Lung. Good job Purdue. Anyway, when he saw that it was safe, I remember fondly how he took loprazolam (Dormonoct) a friend I have in the Netherlands gives to me, really, no darkweb, he's a friend since like 1999 when we were both makers of an mp3 sharing site, like how the Offspring in 2000 only had 2 radio friendly songs on Conspiracy of One and gave all the album for free online, their (forced-upon-them) major label were not too happy. We were a dozen just having ftp sites with links to full albums in a ftp:// link for .rar'd albums. I got some now still, shooting them is amazing, I can only imagine what Versed/whatever name the pilled Midazolam are branded over there. Yeah Loprazolam is just as water soluble. Anyway I remember when he crushed 3x1mg loprazolam, a whole 30mg HMContin mortared beads, 4 or so Dilaudid 4's and ate an oxycontin 80. It was hilarious because he's so addicted (legally) that he just said that the rush of the 3 things at once was crazy, best rush he had in his life (never had heroin either, its just not up here, or if it is, it's some crust punk who moves all over the province who has safe houses where he has a friend at least in every major Quebec towns. Montreal, Longueil, Gatineau, Quebec City, Rimouski, Saguenay, Rouyn-Noranda, Sept-Iles, and the price for the H he had was ridiculous and it was a quick situation where he just came by to give me money he owed my friend, always carrying his bass guitar, the many pouches on it made him less suspicious, he said.
Yeah, I had a little litle memory left small breakdown earlier this week when I was eating clonazolam, shooting loprazolam every 30 minutes and I got majorly uninhibited. It's all good now, gave the flunitrazolam I didn't even take during that time to someone I trust will just keep them for me. I'm swimming in the benzos though, but adding flunitraz to this (which I think I read is water soluble, is it? because if they are...even better idea to give the 20 or so I got left to a trustworthy friend.
